Review on 🎒 MIER 60L/150L Roll Top Dry Bags Duffel - Extra Large Waterproof Backpack Gear for Men and Women: Ideal for Kayaking, Hiking, Travel, and Camping by Richard Marriott

This waterproof 150 liter bag is really huge and therefore somewhat specialized in its usefulness. You're clearly not going to fill it to the brim with rocks, and you can lift it without tearing up the backpack or yourself. Even loaded with average camping gear or accessories, if you can lift it at all, you won't want to carry it up a mountain slope. But what I wanted was to be able to freely stuff an entire family into individually packed sleeping bags and just haul a few tens of meters from home to car or from car to tent. For this purpose it is ideal. For me it's more of an organizer than a carrying device. It's a really nice waterproof material, similar to rubber/vinyl, obviously reinforced with some kind of filament fabric and looks very well built. Seams look very neatly welded or taped under heat and pressure, and there are reinforcement pads at all strap and handle attachment points. A very nice touch is the valve to release trapped air when closing the bag, which can then be screwed down to seal.
